Fig. 6-62 Workstep Wrapped to Become a Process
There are four steps to create a process from an existing workstep.
1 Create a process from your workstep using WorkstepProcessWrapper.
2 When you have a custom UI, enhance the UI behavior.
3 Implement persistence on the workstep argument package.
4 Add your process to the Petrel Process diagram.
Step 1 - Create Process via WorkstepProcess-Wrapper
The Ocean class WorkstepProcessWrapper creates a process from your workstep.
public class WorkstepProcessWrapper : Process
{
public WorkstepProcessWrapper(Workstep workstep);
public object ArgumentPackage { get; }
public Workstep Workstep { get; }
protected override Control CreateUICore();
}
public sealed class Context : WorkflowContext { ... }
Pass an instance of the workstep to the wrapper class constructor.
MyUpscalingWorkstep w = new MyUpscalingWorkstep();
Process p = new WorkstepProcessWrapper(w);
